iio: proximity: pulsedlight: Fix rumtime PM imbalance on error
When lidar_write_control() fails, a pairing PM usage counter decrement is needed to keep the counter balanced. Fixes: 4ac4e086fd8c5 ("iio: pulsedlight-lidar-lite: add runtime PM") Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20210412053204.4889-1-dinghao.liu@zju.edu.cn Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
